Meta-Atoms and Light-Bits

This is about freezing light, mostly so it can be used as memory in photonic computing, which is one of the places we are going with the future of computing, that is, beyond circuits for electric information. The following two articles are just about the ubiquity of quantum mechanical manipulation in increasingly 'normal' circumstances.

Device can theoretically trap a light 'bit' for an infinite amount of time

To overcome light's penchant for escaping, Lannebère and Silveirinha utilized an idea proposed by John von Neumann and Eugene Wigner in 1929, and later extended by others, which has led to the discovery that transparent structures with tailored geometries can perfectly confine light by scattering it in a very specific way.

Lannebère and Silveirinha showed that this strategy for confining light can be achieved by shining light on a spherical "meta-atom," so-named because it allows light to have only a specific quantized energy value (creating a light "bit"), similar to how an atom allows electrons to occupy only certain quantized energy levels.

About Me

First things first, that's not a picture of me, although it could be any one of us. It's a painting by Alex Grey.
Next, the blog Limbic Signal is an extension of my book Hidden Scents, and the blog Network Address is a personal archive that I like to keep online for easy access.
Last, I'm a thirty-something male from Suburbia, New Jersey, a high school visual arts instructor, independent researcher, and writer.
Hidden Scents The Language of Smell in the Age of Approximation is my first attempt at authoring a work of non-fiction, and serves as a response to the dearth of information on the topic of Smell.
